Trust Stem

Stem customers are leaders in their fields. They include more than 30 Fortune 500 companies and represent a variety of sectors, from education to manufacturing. More than 40 existing Stem customers enrolled additional facilities in 2017.

The timing of energy use has never been more critical.

Peak rates are rising, time-of-use periods are moving, and solar policies are in flux – leaving you exposed. But most organizations don’t have the flexibility, speed, or staff to manage energy around-the-clock.

Energy costs in Southern California have been out of control. The savings from Stem have actually turned the situation around. With limited resources, it’s great to know our operation is secure going forward.
